Enjoy high-quality sound system on your PC! The onboard 8-channel HD audio
(High Denition Audio, previously codenamed Azalia) CODEC enables high-quality
audio output, jack-detect feature automatically.

1-4 Chapter 1: Product introduction
Serial ATA 3Gb/s technology
This motherboard supports the next-generation hard drives based on the Serial ATA
(SATA) 3Gb/s storage specication, delivering enhanced scalability and doubling the bus
bandwidth for high-speed data retrieval and saves. Easily backup photos, videos and
other entertainment contents to external devices. See page 1-29 for details.
ATI CrossFire X Technology
ATI’s CrossFire X boosts image quality along with rendering speed, eliminating the need
to scale down screen resolutions to get the high image quality you want. CrossFire X
ignites with the higher antialiasing, anisotropic ltering, shading, and texture settings you
desire. Adjust your display congurations, experiment with your advvanced 3D settings,
and check the effect with a real-time 3D-rendered preview within ATI’s Catalyst™ Control
Center to rule your CrossFire X system.
S/PDIF-out on Back I/O Port
This motherboard provides convenient connectivity to external home theater audio
systems via an optical or coaxial S/PDIF-out (SONY-PHILIPS Digital Interface) jack. It
allows to transfer digital audio without converting to analog format and keeps the best
signal quality.
1.3.2 Innovative ASUS features
ASUS CrashFree BIOS3
The ASUS CrashFree BIOS 3 allows users to restore corrupted BIOS data from a USB
ash disk containing the BIOS le. See page 2-7 for details.
ASUS Q-Fan technology
The ASUS Q-Fan technology smartly adjusts the fan speeds according to the system
loading to ensure quiet, cool, and efcient operation. See page 2-32 for details.

ASUS P5KPL/1600 1-5
ASUS EZ Flash2
EZ Flash 2 is a user-friendly BIOS update utility. Simply press the predened
hotkey to launch the utility and update the BIOS without entering the OS. Update
your BIOS easily without preparing a bootable diskette or using an OS-based ash
utility. See page 2-4 and 2-37 for details.
C.P.R. (CPU Parameter Recall)
The C.P.R. feature of the motherboard BIOS allows automatic re-setting to the
BIOS default settings in case the system hangs due to overclocking. When the
system hangs due to overclocking, C.P.R. eliminates the need to open the system
chassis and clear the RTC data. Simply shut down and reboot the system, and the
BIOS automatically restores the CPU default setting for each parameter.
ASUS MyLogo2™
This feature allows you to convert your favorite photo into a 256-color boot logo for
a more colorful and vivid image on your screen. See page 2-34 for details.
Green ASUS
This motherboard and its packaging comply with the European Union’s Restriction
on the use of Hazardous Substances (RoHS). This is in line with the ASUS vision
of creating environment-friendly and recyclable products/packaging to safeguard
consumers’ health while minimizing the impact on the environment.
ASUS Express Gate
Taking only 5 seconds to go online from bootup, Express Gate is the one-stop gateway
to instant fun! It’s a unique motherboard built-in OS. You can utilize the most popular
Instant Messengers (IM) like MSN, Skype, Google talk, QQ, and Yahoo! Messenger
to keep in touch with friends, or quickly check on the weather and e-mails just before
leaving your house. What’s more, the user-friendly picture manager lets you view
your pictures without entering Windows at anytime!
• The actual boot time depends on the system conguration.
• ASUS Express Gate supports le uploading from SATA HDDs, ODDs and
USB drive and downloading to USB drives only.

1-6 Chapter 1: Product Introduction
Onboard LED
The motherboard comes with a standby power LED. The green LED lights up
to indicate that the system is ON, in sleep mode, or in soft-off mode. This is a
reminder that you should shut down the system and unplug the power cable before
removing or plugging in any motherboard component. The illustration below shows
the location of the onboard LED.
1.4 Before you proceed
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
• Unplug the power cord from the wall socket before touching any
component.
• Use a grounded wrist strap or touch a safely grounded object or to
a metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity.
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.
• Before you install or remove any component, ensure
that the ATX power supply is switched off or the power cord is detached
from the power supply. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.

1.5 Motherboard overview
Before you install the motherboard, study the conguration of your chassis to
ensure that the motherboard ts into it.
1.5.1 Placement direction
When installing the motherboard, make sure that you place it into the chassis in
the correct orientation. The edge with external ports goes to the rear part of the
chassis as indicated in the image below.
Place this side towards
the rear of the chassis
Do not overtighten the screws! Doing so can damage the motherboard.
Ensure to unplug the power cord before installing or removing the motherboard.
Failure to do so can cause you physical injury and damage motherboard
components.
1.5.2 Screw holes
Place six (6) screws into the holes indicated by circles to secure the motherboard
to the chassis.
